โฆ Synopsis
The concept of additivity of individusl resistances to mass transfer between phases is confirmed by experimental measurements of transfer coefficients for vaporization of water into air, and the absorption from air of carbon dioxide, ammonia, and acetone by water. RBsum6-Les expdriences de l'auteur v&iiIent la regle d'additivit4 des resistances individuehes aux kohanges de mat&e entre phases. Les coefficients d'echange ont &A? mesurks pour ia vaporisation de l'eau dans I'air et pour l'absorption par l'eau de gaz carbonique, gaz ammoniac ou acetone melanges S l'air.

The paper examines the commonly used rule for the addition of phase resistances. It is shown that for fluctuating coefficients this rule does not necessarily apply. It is thought, however, that the error involved is not iarge enough to be important for most practical applications.
